Further, a window 16 that can be opened and closed may be arranged on the upper wall of the window body. In this method, by opening and closing the window 16 as needed, the corresponding operation can be easily executed in the window main body 1. For example, the functional module in the window main body 1 is incorporated through the window 16. Or it can be replaced.

In the present invention, the window body 1 corresponding to the wound healing site is located at the functional wound healing site where the free skin edge is positioned in the middle of the wound, and thus the functional healing site and periphery of the wound. The placement of the window body 1 structure achieves effective, reliable, stable and robust structural separation between the non-functional wound healing site and thus various important functional modules in the window body 1 structure for wound healing. It can act consistently, more reliably, stably and directly at the site and function more effectively without external adverse interference, thus promoting good physiological healing of the wound. ..

The fixture 3 is positioned on the skin 15 on both sides of the wound midline and the skin 15 on both sides of the wound midline is fixed by an adhesive layer. After the fixture 3 is articulated with the zipper 2, the zipper 2 brings the fixture 3 and skin 15 on either side of the wound closer to the window body 1, thereby closing the wounds on both sides of the wound toward the center of the wound. Driven like.

The upper wall of the window body is made of a soft material and can sink downward under the action of negative pressure. A window 16 that can be opened and closed is arranged on the upper wall. When the window 16 is open, the interior of the window body 1 is open and visible, thus incorporating or replacing the functional module within the window body 1 to hemostasis the wound, exudate and on the skin 15 at the wound site. A visible open treatment of juxtaposed wounds can be achieved.

When the window 16 on the upper wall is open, the juxtaposed reference support module 8 can be precisely placed on the wound surface, and the wound-facing bottom of the juxtaposed reference support module 8 is a rigid reference plane 9. This can ensure that the upper wall sinks downward under the negative pressure synergistic effect of the window body 1 while the zipper 2 allows lateral juxtaposition towards the wound midline of the wound. The wound is adhered to the reference plane 9 of the rigidity of the reference support module 8 juxtaposed in the vertical axis of the wound without any discrepancies and gaps to achieve layered juxtaposition of the wound in the vertical axis of the wound. A flat standard state of the rigid reference plane 9 is achieved, which can guarantee layered juxtaposition of the wound in both the horizontal and vertical axes according to the original anatomical structure of the skin 15. The opening and closing structure of the window 16 can be realized by using an opening and closing structure such as a flip open sash, a slide open cover, a removable open cover, a snap-on cover or a zip. The shape of the window 16 can be designed into a rectangle, circle, or a special shape adapted to the wound, based on the length and shape of the wound or treatment module to be placed. The window 16 can be flexibly set as an integrated opening / closing or a partially independent opening / closing, if necessary.

The wound closing device further comprises a negative pressure sealing film 4 at the first site and a negative pressure sealing film 5 at the second site, and the negative pressure sealing film 4 at the first site and the main body wall of the window. It is enclosed so as to form the negative pressure seal chamber 6, and the seal film 5 of the second portion, the outer wall of the window body 1 and the surrounding skin 15 are enclosed so as to form the peripheral negative pressure seal chamber 7. And the fixture 3 is aligned in the peripheral negative pressure seal chamber 7. Specifically, in order to facilitate independent operations at different sites and to achieve different functional therapeutic objectives, in the present invention, the negative pressure seal film 4 at the first site and the negative pressure seal at the second site. Two independent double negative pressure seal chambers are formed from film 5. In this separate window negative pressure seal chamber 6, doctors can more stably, reliably, consistently and effectively perform their functions of wound healing modules without external adverse interference. Thus, functional modules for wound healing can be easily fixed to the wound healing site in sequence or in combination by simply opening and closing the window 16 so that good physiological healing of the wound can be promoted. .. At the site of the peripheral negative pressure seal chamber 7, the doctor can independently operate the string body 14 or the protrusion 13 of the zipper 2 to adjust the juxtaposition of the surrounding skin 15. The wound juxtaposition performed by the lock is unaffected by the overall negative pressure relief when the treatment operations associated with the wound healing site are performed independently. The wound juxtaposition state maintained by the juxtaposed reference support module 8 in the negative pressure chamber of the window body 1 and the therapeutic function and therapeutic effect consistently and stably provided by the functional wound healing module in the window body 1 are locking forces. Is not affected even if is adjusted independently. A wound closure device with a double negative pressure chamber will eventually completely remove bleeding and exudate from the wound, and a juxtaposed reference platform will adhere to the top surface of the wound under sustained negative pressure action. It can be assured that it can be pressed, thus avoiding the shedding of the suture device due to the accumulation of exudate, suture failure and secondary wound infection.

In the present invention, the main body wall is an annular closed separation enclosure. The separation enclosure causes the suture device to fall off due to the accumulation of exudate, suture failure and secondary wound infection, resulting in non-healing or delayed healing, the wound exudate flowing out and the fixture 3 on the outside of the window body 1 and It can prevent infiltration into other structures.

In the present invention, a shaper structure is specially attached to the separation enclosure. The geometry of the shaper (processed part, forming part) can be pre-manufactured according to the actual shape of the wound, and further, the actual midline of the wound to match the actual shape of the wound. It can be more flexibly pre-manufactured into a closed ring shape that extends a predetermined distance to both sides of the wound along. The shaper geometry determines the final geometry of the separation enclosure, so that the treatment modules placed at the functional healing site consistently perform their function without external reverse interference. Precisely pre-manufacture functional wound healing sites of various shapes so that they can be performed more effectively, reliably, stably and directly, and thus promote good physiological healing of the wound. It is possible to achieve precise customization and effective separation of functional wound healing sites. On the other hand, by realizing the geometry of the pre-manufactured shaper, the wound closure device can be "curved, S-shaped, L-shaped, Z-shaped" and many other irregular wounds. It can be better adapted to clinically non-linear wounds with precise customization and effective separation of functional healing sites. As a practical and beneficial result, the range of products for treating clinical wounds is greatly expanded, and in addition, the challenge of suturing irregular clinical wounds is solved.

In the present invention, the zipper 2 is a ratchet structure or a string structure 14. The ratchet structure comprises a lock catch 12 and a protrusion 13, the lock catch 12 being articulated to the fixative 3, and the ratchet is disposed within the lock catch 12 so that the protrusion 13 slides outward in one direction. To limit, one end of the protrusion 13 is connected to the window body 1 and the other end is inserted into the lock catch 12. The ratchet of the lock catch 12 may limit the protrusion 13 from sliding outward in one direction. It is also possible to pass the lock catch 12 and the protrusion 13 through the negative pressure seal film 5 at the second portion, so that the lock catch 12 and the protrusion 13 are arranged on the outside of the seal film for ease of operation. It is possible. The skin 15 on either side of the wound can be shrunk to the middle by pulling on the protrusion 13. The string body structure 14 includes a string body 14 that is folded back at a connecting portion with the window body 1 to form a folded portion, and the folded portion of the string body 14 is connected to the front surface of the fixture 3 and the back surface of the string body 14. An adhesive site is provided for fixing. The string 14 may be pulled in the opposite direction to drive the skin 15 to the center, so that the adhesive site of the string 14 can be operated more easily and conveniently by arbitrarily adjusting the pulling distance. As such, it is possible to be bonded and fixed anywhere in the adhesive structure on the back surface of the string body 14 and the top surface of the fixture 3.

The string 14 may further be constructed in a thin and flat structure, so that the flat string 14 may be more easily placed in the surrounding negative pressure chamber due to the limited space. It is possible.

Fixtures 3 are arranged on both sides of the window body 1, and the bottom of the fixture 3 has an adhesive layer for adhering and fixing to the surface of the peripheral skin 15 on both sides of the wound toward the skin 15. At the edge of the fixture 3 formed, a baseband 11 parallel to the corresponding outer wall of the window body 1 is placed towards the inside of the wound.

Better suture many irregular non-linear wounds such as "curved, S-shaped, L-shaped, Z-shaped" and other irregular wounds that are clinically difficult to treat with conventional sutures Therefore, the fixative 3 may be further arranged in separate parts (areas), and the inner baseband 11 of each of the separate parts of the fixture 3 is parallel to the corresponding outer wall portion of the window body 1. Be placed.

The baseband 11 is a rigid linear skeleton that can pull the skin 15 on both sides of the wound evenly in parallel so as to approach the median line, at each part of the wound when suturing an irregular wound. Guarantee uniform juxtaposition. The baseband 11 collects the suturing force of each separate portion and transmits it to the corresponding portion of the window body 1 via the zipper 2. On the other hand, the baseband 11 linearly applies the high suture force collected between the window body 1 and the fixture 3 to the surface of the skin 15 that is attached to the fixture 3 and the fixture 3 along the baseband 11. It also disperses evenly to prevent the high suture stress of the closure device from being over-concentrated or concentrated on the local skin 15 of the wound, which can result in corresponding stress damage to the skin 15. For example, suture tension during suturing is concentrated at the puncture point of the skin 15, which inevitably causes cut damage to the skin 15, or suture runout and suture failure. If the wound is only closed with a low tension butterfly closure strip, severe tension vesicles and other damage to the skin 15 develop at the base of the butterfly wing and treatment cannot be continued. Therefore, by placing the baseband 11, it is possible to better avoid suture failure or interruption of treatment of the wound.

In the internal space of the window body 1, there is a wound exudate absorption module that can absorb the wound exudate, a wound hemostatic module that can help stop bleeding from the wound quickly, and a wound bacteriostatic that can effectively avoid the growth of bacteria. And functional treatment modules are deployed, including antibacterial modules, wound information acquisition modules that can obtain wound information in real time using sensors, and cell tissue regeneration modules that can promote wound healing. The sash (frame) of the window body (opening body) 1 makes full use of the function of the treatment module, enhances the efficiency of wound treatment, and various functional treatments in the wound healing process for symptomatic treatment and targeted treatment. Practice at different stages of wound healing, depending on the actual condition of the wound or based on treatment needs, in order to rationally customize the scheme for using the module and promote good physiological healing of the wound. Depending on the clinical or actual functional needs of the treatment, it is arranged to facilitate operation and to fix the treatment modules individually sequentially or in combination.

The wound closure device further comprises a negative pressure pipeline that communicates the negative pressure seal chamber 6 of the window (opening) and the peripheral negative pressure seal chamber 7 with the outside. The negative pressure pipeline is equipped with a valve that communicates with the outside of the negative pressure seal film so that bleeding and exudate from the wound can eventually be removed, and the juxtaposed reference platform is a wound under negative pressure action. It is guaranteed that it can be pressed in close contact with the top surface of the. A wound closure device with a double negative pressure chamber can be adhered to the wound skin 15 without separation.

In conclusion, a stable and sturdy separation window body 1 structure is placed within the functional wound healing site, so that the built-in functional treatment module consistently makes the functional therapeutic effect more effective and reliable. , Stable and can be given directly. The placement of the juxtaposed reference support module 8 further ensures layered horizontal alignment and vertical juxtaposition in both the horizontal and vertical axes of the wound, according to the original anatomy of the skin 15. The window 16 that can be opened and closed on the window body 1 further meets the needs of physicians who use the required functional modules individually or in combination depending on the actual condition of the wound, as well as wound healing schemes and symptomatic treatments. Achieve personalized customization of targeted treatment. Pre-manufactured shapers on the window body 1 can better meet the precise customization and effective separation of functional healing sites for wounds with diverse and irregular geometries, and even more irregularly. It can solve the problem of suturing clinical wounds with various geometric shapes. As a result, adverse or secondary damage such as suture device dislodgement, wound suture failure and secondary wound infection resulting from the accumulation of exudate in other closure devices can be effectively avoided and thus good wounds. Physiological regeneration and healing can be achieved with higher efficiency and better effect.

The present invention constructs a complete or non-interfering treatment unit at the wound healing site positioned in the middle of the wound, thus ensuring, consistently and consistently with the functional modules required for wound healing at the wound healing site. It provides a more effective wound closure device that can act directly. Specifically, the solid structure of the window body 1 is used to separate the functional healing site in the middle of the wound from the adhesive fixation site around the wound, thus promoting good physiological healing of the wound. A variety of important functional modules that can be placed independently within the structure of the window body 1 and the functional modules within the window body 1 are separated without interference from peripheral sites, consistently and reliably at the wound healing site. It can act stably and directly, effectively avoiding the loss of the suture device resulting from the accumulation of exudate, secondary wound infection, wound suture failure and wound healing of inconsistent malformations. In addition, better physiologic regeneration and healing of wounds is achieved.
